'f`

To the crank-pin of' th-ewheel E pivoted one end of the connectingbarJ,:thc otherend of which is pivoted to the sliding barvK, so that thesaid bar may be' moved back and forth by the advance of the' machine. Tothe bar K are attached plates, L, which pass throughfa slot in the frontbar of' the frame A, and ex# tend beneath the open bottoxn'of thehoppers M, said plates being made of such a ybreadth as toghe alwaysbeneath said'ihoppers as they m'ove hackandY forth. Y '1 he hoppers Mrestfupon and are'securedto the bottomboards N, which are attached tothe frame A, and which" have holesformed through them correspondinginshape and size with the open'bottom of the hoppers,` so-that the saidholes I nay4 be, in fact, a continuation of the interior of thehoppers.l

The plates L fit into,`and move back and forth in, thespaceA betweenthe-boards N and the boards O, alsopattached to the frameA.

' In the plates L are iormed'holes,'into which are tted cups, P, which'lnay be made of Vdilierent sizes, 'according to the size of seed'andthe amount of seed to be dropped for-a hill.v

The cups .P are so placed inthe plates L that when the said plates L aremovedv vin one direction by the movement of the bar K the cups P, passbeneath the open lower end of the hoppers M and become lled with seed. A

'As the plates L are moved in thel other direction the filled cups P arecarried between the boards N and O, andthe seed drops through Aholes in"gthe lower boards O and falls into the open upper ends 4of the spoutsQ, by 'which itis conducted to the ground.

.isa shaft that works in bearingsattached to the frame A, a'ud .toWhichthe upper ends 4of theconductor-spenteA Q are attached, by-means.oi'"iron straps,

which. pass around and are secured tothe uppeends of said spouts, andtheendsof which are'passed through vthe said shaft R, are slightly bent,and are secured in place by'a vWedge driven 4between `the said ends.

. 'lotlie forward sides of the spouts Q is riveted a bar, S, to which isrivetedor-otherwisefsecnred the braces T, the upper ends of'which .aresecured to the shaft R. y

To the lower eud of the bar S is secured a plow, U,

for opening a furrow to receive the seed.

ToA the lower end of the har S are also secured the Wings V, which arecurved to pass around' the lower end of the spouts Q, and project atitsrear side, and ther-ear ends of.. which project downward to escapedown the sides of the furrow, and ll it, thus covering-'the seed.

The shaft Ris turned to raise the lower ends ofthe tachedto the saidshaft 1t,and the upper end of which 'l projects upward into such aposition that" it may be planting will always be in perfect check-row.

conveniently reached and operated by the driver from his sea-t.

'X is a notched catch-bar or plate, attached to the frame A orto theseat-support Y, to receive and hold the lever W in its diierentpositions.

The seat-support Y is so formed ,as to serve as a tool-box, and toit areattached the springs upon which the seat Zrests.

To the under side of the .bar K are attached two short rack-bars, A',into the teeth of which mesh the teethoi' lthe segmental gear-wheels B',which are secured to the outer ends of the shafts O1, which workiu'bearings attached to the frame A, and to the other ends of which areattached, or upon them are formed,

cranks D', to the crank-arms of which are pivoted the upper ends of theconnggst-ing-rods or bars E', the other ends of which are pivoted to thebar or beam F', so as to suspendV thel said bar or beam iu such a waythat it may be raised or lowered alternately at regular intervals by theadvance of the machine.

To the underside of the bar or beam F are attached two jointed arms, G',viii such positions as to be di,

reetly in the rear ofthe sponts Q, which, as the bar or beam F islowered, strike the ground and mark the hills.

To the upper side of the bar or beam F' are attached arms, H', whichpass up through guide-holes in the frame-work of the. machine,to cansethe said bar o beam F' to move-up and down yertically.

The machine should be so made that the wheels may be twice as far apartas the distance between the rows, and the sponts at a distance apartequal to the distance between the rows, said spouts being equallydistant from theiradjacent wheels.

By this vconstruction the inner wheel may, each time of crossing thefield, follow the track of the outer wheel in the nextprevious crossing,the wheel-tracks thus serving as guides to the drivel', andenablingljim, without previously marking the ground, to keeplhis rowsparallel. At thesametime the hill-markers'enable him to keep his machineso adjusted that the Togreuder my machine more serviceable to the farmerI have adapted it to be used as a cultivator, with slight or easily-madechanges in the `working parts. To the cultivator attachment, however, Ido not here lay claim. y

In making the chaugeto adapt the machine to operate as a cultivator, thedroppingvdevices are. detached and the plow-frame, shown in figs. 4- and5, attached.

1 are the plow-plates, which are attached to or formed upon an arm orstandard, J', which passes up through the beam K', and is` secured inplace by a nut screwed upon its upper end.

. The forward ends of the plow-beams K', six, more or less, of which maybe used, are pivoted to a. long bar, L'.

The plow-beams K are secured in place, when adjusted, by bolts, whichpass through them and through slots in the bar or beam M', and aresecured by nuts.

The bar or beam L' is connected to the shalt R by bands or clevices, N,which pass around the said shaft R and are bolted to the said bar orbeam L.

O is a hook pivoted to the bar or beam M', and which is hooked upon thelever lV, or into a hole formed in the said lever. to enable the plowsto Abe raised from the ground when desired, by operating the said leverW.

P' are guard or fender-wheels, which are made as shown in ligs. 4 and 5,and which are designed to prevent clogs, stones, and otherl substancesfrom being thrown-against the plants by the adjacent plows, and thusinjuring them, while allowing the line soil to pass fi eely to andaround the said plants through the openings in said wheels.

The wheels I are revolved by contact with the ground, and are attachedto the opposite ends of a short shaft, Q', so that the said wheels maywork one upon each side ofthe row of plants being cultivated.

The shaft Q' revolves in bearings inthe end of a' bar or arm, R',attached to the center of the bar or beam M', A

S' is the tongue, which is securely attached to the frame Aof themachine, at one side of its centralpoint, to balance the. side-draft.

'l"is a small roller, pivoted to the lower side of the tongue S', by abolt, in such a position as to rest against the forward side ofthesliding lbar K, and keep it and the plates L in proper position whilebeing operated.

Having thus described my invention,

l claim as new and desire to secure by Letters Patent- 1. Thecombination of the cups P, sliding plates L, sliding'bar K,connecting-bar J, .crank-gear wheel E, gear-wheel l), and roller T',with each other and with the boards N 0, hoppers M, frame A, wheel C,and tongue S', substantially as herein shown and described, and for thepurpose set forth.

2. The combination of the shaft R, sponts Q, bars S, braces'T, plows U,covering wings V, lever W', and catch-bar or plate X, with each otherand with the bottomA boards N O, sliding plates L, sliding bar K,couuectingbar J crank-gear wheel E, gear-wheel D, wheels C, and frame A,substantially as herein shown vand described, and for the purposes setforth.

3. The combination of the racks-A', gear-wheels B', shaft 0', cranks D',connecting-bars E', bar F', jointed arms G', and guide-arms H', witheach'lother and with the frame A andV sliding bar K, substantially asherein shown and described, and for the purpose set forth.
